Abstract
This letter presents a touch‐driven self‐powered sensing system utilizing a high‐performance thermoelectric generator (TEG). The TEG, employing assembly technology with a high‐performance electrodeposited thermoelectric material, is fabricated. This device is accompanied by an investigation into the associated electronic circuits, facilitating a realistic demonstration. Upon tactile interaction with one side of the TEG, the system efficiently harvests energy, accumulating 15.36 mJ in a storage capacitor. Energy consumption, inclusive sensors and Bluetooth Low Energy (BLE) communication, is evaluated at 0.75 mJ/cycle, with a 2 s interval time. Notably, the sensing system demonstrates sustained operation as long as touch interactions persist, showcasing its potential for continuous, self‐powered functionality. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.
